Emissions of all HFCs are included in the UNFCCCs Kyoto Protocol. HCFC-22 (CHClF2) and HFC-134a (CH2FCF3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. We find pronounced seasonal variations of global emissions for these two major refrigerants, with summer emissions two to three times higher than in This study presents the quantification of the emissions of the refrigerants CFC-12 (CCl2F2), HCFC-22 (CHClF2), and HFC-134a (CF3CH2F) from road traffic in Switzerland. These gases are used as refrigerants in car air conditioning systems (A/C-systems) and in cool aggregates for refrigeration transpor … CHLORODIFLUOROMETHANE: ICSC: 0049: HCFC-22 R-22 Freon R22 Monochlorodifluoromethane Methane, chlorodifluoro-HCFC 22 R 22: July 2002 Learn more about the 2016 inclusion of a global HFC phase down the Montreal Protocol - that now has two regimes to control; the ODP and the GWP substances. In 1993, the EPA established the phaseout framework and the "worst-first" approach that focused first on HCFC-22, HCFC-141b, and HCFC-142b because these three HCFCs have the highest ODPs of all HCFCs. To meet the required 2004 reduction, the EPA phased out HCFC-141b in 2003 and froze the production and consumption of HCFC-22 and HCFC-142b.

Known as Chlorodifluoromethane or difluoromonochloromethane R22 is a hydrochlorofluorocarbon (HCFC). While it is being phased out in many countries it is still used in some other. While it’s predecessor Freon 11 was a higher threat to the ozone layer, now even R22 is considered dangerous for the environment.
Implications of the establishment of new hydrochlorofluorocarbon-22 (HCFC-22) facilities seeking to obtain certified emission reductions for the destruction of Here we examine chlorodifluoromethane (HCFC-22), a chemical designated as toxic in 1994 by the U.S. Environmental Protection Agency's Toxics Release Environment Canada seized more than $1 million of illegally imported HCFC-22 ( R-22) refrigerant this spring.

The retrievals of these species from the FTIR spectra are sensitive from the surface to approximately 20 km, while the ACE-FTS profiles extend from approximately 6 to 30 km. The plan is set to completely phase out the R22 refrigerant as well as the common refrigerant blends that contain HCFC-22 by the year 2030. This includes the R-401A, R-402A, R-408A, R-409A, R-414B, and the R-502A refrigerants. (There are actually a total of 34 HCFCs being phased out). By January 1, 2015, the ban on the production, import, and Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC).
